I’ve gotten complaints from a bunch of commenters about problems with comments getting thrown into the moderation queue by the spam filter. Things with too many links, or with certain text properties, were getting caught even though they are clearly not spam.

In order to get around this, I’ve re-enable typekey authentication. You don’t *have* to login via typekey to post comments – it’s entirely voluntary. But you’re welcome to if you want, and if you do, your posts will be almost guaranteed to get posted without being pushed into the mod queue. (If you write a post containing links to viagra-selling websites, you’ll still get trapped by the spamfilter. But anything less egregious than that should go right through.

Blake StaceyI don’t see the TypeKey link. Isn’t it supposed to appear under “Post a Comment”?

Blake StaceyAha, now it shows up (on a different computer). Either it was just re-enabled, or I’ve got my Adblock settings

TypeKey managed to sign me out before I could post this, so an extra copy will be lurking in the spam queue.

AnonymousWell, now I feel

reallybad. My heroic struggle with TypeKey left three almost-identical messages when I had hoped to post only one; I’m not quite sure how that happened.AnonymousFurthermore, while it says “Thanks for signing in, Blake Stacey” above the comment box, my messages appear signed by “Anonymous”. Grrrr.

Ørjan JohansenWhile there is a meta thread here, is there some way of getting a page with a longer list of recent comments? Even with checking this blog once a day the list still flushes off the end from the comments in the more inflammatory bad math threads, which I usually skip. So I end up checking the smaller good math threads by hand, usually with nothing new in most of them.
